Hello, fellow Lifehackers! Time for another MacGyver Challenge. What's a MacGyver Challenge, you ask? Simple. We give you an object and you show us what cool things you can do with it. Our editors pick the best submissions and our favorite will win an autographed copy of the Lifehacker book!

Now, it's your turn. Show us your best hack using an empty can or bottle. Your hack can use other materials, of course, but the bottles or cans should be the defining element. Send us pictures and a description of your hack and feel free to annotate your photos if you need to. And don't be afraid to get creative!

How to Submit Your Entry

Make sure to follow these instructions when you submit your entry:

Post your entry below or send it to challenge@lifehacker.com with the subject MacGyver Challenge: Bottles or Cans. If you post your entry below and need to include more than one image, just reply to your own comment or host your extra pics on a free, quick image-hosting site like imgur and link out to your gallery.

We will accept entries up through Sunday night, December 2 at 11:59pm Pacific Standard Time

We will showcase the best submissions and announce our favorite Monday, December 3.

So grab that leather flight jacket, comb your mullet, and start channeling those MacGyver vibes. Here's a little theme music to put you in the mood. And don't forget to check back every week for a new challenge. We'll be alternating between Hacker Challenges and MacGyver Challenges.

Update: We didn't get a ton of nominations last week, presumably because of the holiday, so we're giving you guys one more week to submit entries for this one! We'll showcase the winners next week on Monday, December 3.
